RE: Seneca II-W Mine(Permit No. C-1982-057)(HC#68680)
Dear Ms. Reilley,
Thank you for your correspondence dated July 2,2020 and received by our office on July 10,2020 regarding
the review of the above referenced undertaking under Section 106 of the National Historic Preservation Act
(NHPA)and its implementing regulations 36 CFR Part 800.
After review of the documentation provided,we note that in accordance with the 1991 Memorandum of
Understanding(MOU)between our agencies concurrence between our agencies is required due to the potential
for impacts to cultural and/or historic resources. After review of the MOU,we note that not only was it signed
29 years ago,but the only amendment(containing categorical exclusions)was made 17 years ago. We suggest
that our offices collaborate in the near future to assess the continuing usefulness of the MOU and the
possibility of terminating the MOU and creating a Programmatic Agreement or several Programmatic
Agreements tailored to the specific needs of the various resource types managed by your office.
As the proposed pen-nit renewal does not involve any new surface disturbance or modify the approved mining and
reclamation plan,we find that a finding of no historic properties affected[36 CFR 800.4(d)(1)]is appropriate for
the proposed activities.
Should unidentified archaeological resources be discovered in the course of the project,work must be
interrupted until the resources have been evaluated in terms of the National Register eligibility criteria(36
CFR 60.4)in consultation with our office pursuant to 36 CFR 800.13. Also, should the consulted-upon scope or
proposed work change,please contact our office for continued consultation under Section 106 of the National
Historic Preservation Act.
We request being involved in the consultation process with the local government,which as stipulated in 36
CFR 800.3 is required to be notified of the undertaking, and with other consulting parties. Additional
information provided by the local government or consulting parties might cause our office to re-evaluate our
eligibility and potential effect findings. Please note that our compliance letter does not end the 30-day review
period provided to other consulting parties.
Thank you for the opportunity to comment. If you have any questions,please contact Matthew Marques,
Section 106 Compliance Manager, at(303) 866-4678, or [e-mail].
Sincerely,
Dr. Holly K Norton Digitally signed by Dr. Holly K Norton
